Ok, quick and probably dumb idea how one could write a "ZLinkBot".

If there is a central part in zope (ZPublisher?) which always runs when 
methods/scripts/etc  are called, one could patch it to also log the path 
of the object which is called (the physical path!).
Then just use a web spider which crawls the whole site, and after that 
compare the list which has been produced by the method above to the list 
of objects in your ZODB.

Everything which hasn't been touched is an orphan.

Could ZPublisher.Publish.call_object() be that central piece of code?
